I found a 19-pin air needle scaler for sale online that I think might be just the thing to help me remove all the concrete-like road crud from the frame of my 1951 half ton I'm trying to coax into a street rod. The grease, mud and dirt has hardened into really thick, hard crud that's difficult to remove. Anyone have any experience with one of these and do they really work good?

Thanks
